Identifying and definitional attributes
|Metadata item type:||Indicator|
|Short name:||National Bowel Cancer Screening Program adverse events (hospital admission rate)|
|Synonymous names:||NBCSP adverse events (hospital admission rate)|
|Registration status:||Health, Standard 06/09/2018|
The proportion of people who returned a positive National Bowel Cancer Screening Program (NBCSP) screening test and had a diagnostic assessment in a defined 12-month period who were admitted to hospital within 30 days of the assessment, measured 6 months after the defined period.
As with any invasive procedure, there is the risk of an adverse event occurring with a colonoscopy or other diagnostic assessment.
Maximising benefit and minimising harm is an important tenet of population screening. Accordingly, it is important to report the known harms from screening when monitoring the performance of the program. Further, many international colorectal screening programs report this indicator, which would bring Australian monitoring in line with International programs and allow comparisons to be computed if required.
To operationalise the monitoring of adverse events, the rate at which people who had a diagnostic assessment in a 12-month period were admitted to hospital within 30 days of that procedure should be monitored.
To reduce the effect of any lag time between invitation, positive screen, and diagnostic assessment (with adverse event), this indicator includes all those who had a diagnostic assessment in the defined period, not all those invited in the defined period (who had a diagnostic assessment).

Data source attributes
|Further data development / collection required:|
Adverse event data are collected within the NBCSP for those undergoing assessment; however, return of these data to the NBCSP register is not compulsory, meaning they may be incomplete. These NBCSP register data will be used until a more accurate and complete data source is available.
The indicator will be reviewed at the completion of the biennial screening rollout, or earlier if program changes warrant it. The NBCSP adverse event data, while potentially incomplete, only contain true adverse events.
